Claims (10)

1. A device for flushing (1) a cistern, which contains a supporting structure (3) that extends along the axis (A); the valve body (4) which extends and can slide along the axis (A) and is equipped with a closure (5) that works together with the seat of the seal (6) of the supporting structure (3); the float (7), which is fixedly installed with the valve body (4) and is movable together with the valve body (4) in relation to the supporting structure (3); an actuation system (9) connected to the valve body (4) to lift the valve housing (4) and open the seal seat (6); a float (7) which protrudes laterally from the valve body (4) and which is placed eccentrically and radially outwards in relation to the valve body (4), wherein the device is indicated by the fact that the float (7) is set to slide in the tank (22) supporting structure (3) which is placed eccentrically with respect to the axis (A); and that the container (22) regulates the rate of fall of the valve body (4) and has a valve (27) for supplying water to the container (22) and at least one outlet opening (30; 28b) for the outflow of water from the container (22). 2. Device according to claim 1, characterized in that the valve (27) is a one-way valve located in the lower part of the container (22), especially on the lower lower wall (24) of the container (22), and designed to allow water to enter upwards into the tank (22) and to prevent the water in the tank (22) from flowing down. 3. Device according to claim 1 or 2, characterized in that the container (22) is equipped with an auxiliary opening (28b) that bypasses the valve (27). 4. Device in accordance with one of the previous patent claims, characterized in that the container (22) is equipped with a first window (30) that determines the first opening for water exit from the container (22), the first window (30) is formed in the side wall (25) of the tank (22) and is at a higher level than the valve (27). 5. The device according to patent claim 4, characterized in that the first window (30) is equipped with a first adjustable door (31), movable to adjust part of the flow of the first window (30) and thus to adjust the flow of water from the tank (22) . 6. Device according to one of the previous patent claims, characterized in that it additionally contains a ballast tank (8) which contains water and which can be selectively connected to the valve body (4) for performing partial flushing and a ballast tank (8) which is placed laterally in relation to the valve body (4) and diametrically opposite to the float (7). 7. Device according to claim 6, characterized in that the ballast tank (8) has a second window (58) equipped with another adjustable door (60) that can be moved to change the opening of the second window (58) and the amount of water inside the ballast tank (8), and thus the weight of the ballast tank (8). 8. Device according to one of the previous patent claims, characterized in that the float (7) contains a floating housing (36) which is generally parallel to the valve body (4) and is radially offset from the valve body (4) and a connecting support ( 37) which passes laterally from the valve body (4) and supports the floating housing (36) in the tank (22). 9. Device according to one of claims 1 to 7, characterized in that the float (7) contains a floating housing (36), at least partially located in the tank (22) and which can slide parallel to the shaft (A) in the tank 22 ) like a piston; the floating housing (36) is closed at the bottom and has a lower end with a surface (38) facing the lower wall (24) of the container (22). 10. Device according to patent claim 8, characterized in that the floating housing (36) is at least partially located inside the container (22) and can slide parallel to the axis (A) in the container (22) like a piston; the floating housing (36) is closed at the bottom and has a lower end with a surface (38) facing the lower wall (24) of the container (22).
